Question: Why Star Topology Is Best?

What are the advantages of a star topology?

Advantages of Star TopologyEasy to install and wire.No disruptions to the network when connecting or removing devices.Requires more cable length than a linear bus topology.If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in computer network communication.More items….

What is advantage and disadvantage of star topology?

The disadvantages of a star network are: it is expensive to install as this type of network uses the most cable (network cable is expensive) extra hardware is required (hubs or switches) which adds to cost. if a hub or switch fails, all the devices connected to it will have no network connection.

Which topology is the best?

A Star Network Topology is best suited for smaller networks and works efficiently when there is limited number of nodes. One has to ensure that the hub or the central node is always working and extra security features should be added to the hub because it s the heart of the network.

What is star topology with diagram?

A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.

What means topology?

In mathematics, topology (from the Greek words τόπος, ‘place, location’, and λόγος, ‘study’) is concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling and bending, but not tearing or gluing.

What are the advantages and disadvantages of topology?

Due to its centralized nature, the topology offers simplicity of operation. It also achieves isolation of each device in the network. Adding or removing network nodes is easy, and can be done without affecting the entire network. Due to the centralized nature, it is easy to detect faults in the network devices.

What is hybrid topology?

Hybrid topology is an integration of two or more different topologies to form a resultant topology which has many advantages (as well as disadvantages) of all the constituent basic topologies rather than having characteristics of one specific topology.

Why star topology is better than bus topology?

1. Star topology is a topology in which all devices are connected to a central hub. … In star topology if central hub fails then whole network fails. In Bus topology the failure of the network cable will cause the whole network to fail .

Which topology is fastest?

But in mesh topology each devices are connected to other devices directly by individual cables without using center hub. Theoretically the fastest topology should be mesh topology. But the best topology is star topology.

Bus topologyWhich type of network topology is least popular? Bus topology is the type of network that contains a common communication line or cable called bus, and all the computers are connected to the bus. The bus topology is least popular because: Breaks in the communication line or cable can disable the entire network.

What are the star topology explain?

In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. The star network is one of the most common computer network topologies. The hub and hosts, and the transmission lines between them, form a graph with the topology of a star.

How is star topology connected?

In star topology, each computer is connected to a central hub using a point-to-point connection. The central hub can be a computer server that manages the network, or it can be a much simpler device that only makes the connections between computers over the network possible.

What are the disadvantages of a mesh network?

Disadvantages Of A Mesh TopologyComplexity. Each node needs to both send messages as well as act as a router, which causes the complexity of each node to go up pretty significantly. … Network Planning. … Latency. … Power Consumption.

What are the key features of star topology?

Characteristics of a star topology are as follows: All cables run to a central connection point. If one cable breaks or fails, only the computer that is connected to that cable is unable to use the network. A star topology is scalable.

Which topology is most fault tolerant?

mesh topologyA mesh topology has multiple connections, making it the most fault tolerant topology available. Every component of the network is connected directly to every other component. Characteristics of a mesh topology are as follows: A mesh topology provides redundant links across the network.

Why switch is called an intelligent hub?

The reason switches are known as intelligent hubs is because they build address table in hardware to keep track of different hardware addresses and the port to which each hardware address is associated. The reason why they are compared to hubs because a switch, when started fresh, acts just like a hub.

Which topology is most reliable and why?

Mesh Topology This topology is divided into two different types; full-mesh and partial mesh. A full mesh topology provides a connection from each node to every other node on the network. This provides a fully redundant network and is the most reliable of all networks.

Where is star topology used?

Star Network Topology Star network topologies are common in home networks, where the central connection point may be a router, switch, or network hub. Unshielded Twisted Pair (UTP) Ethernet cabling is typically used to connect devices to the hub, though coaxial cable or optical fiber may also be employed.

Which topology is mostly used?

star topologyA star topology is the most commonly used network configuration. In this type of topology, nodes are connected to a central device like a switch or a hub with the help of coaxial cable, optical fiber, or twisted pair cable.

Which topology is the most secure?

Star TopologyAdvantages of Star Topology Because each of the nodes is independently connected to the central hub, should one go down, the rest of the network will continue functioning unaffected, making the star topology a stable and secure network layout.
